Abstract
A web-member cutting apparatus for cutting a web member at intervals in a transport direction includes: an intermittent transport mechanism for intermittently transporting the web member in the transport direction; a disc-like rotatable blade member for cutting the web member by moving along an intersecting direction while rotating about a rotation shaft during a suspension period of transport of the web member, and a downstream pressing member for regulating movement of the web member by pressing the web member against the intermittent transport mechanism at a position downstream from a target cut position in the transport direction throughout a period during which the rotatable blade member is cutting the web member.
Claims11
A web-member cutting apparatus for cutting a web member at intervals in a transport direction,
- the web member having a plurality of fibers including tows along the transport direction and being continuous in the transport direction, the web-member cutting apparatus comprising:
- an intermittent transport mechanism for intermittently transporting the web member in the transport direction;
- a disc-like rotatable blade member positioned for cutting the web member by moving along an intersecting direction while rotating about a rotation shaft during a suspension period of transport of the web member without the rotatable blade member engaging an opposing member,
- the intersecting direction intersecting the transport direction,
- the rotation shaft extending along the transport direction;
- and
- a downstream pressing member that regulates movement of the web member by pressing the web member against the intermittent transport mechanism at a position downstream from a target cut position in the transport direction throughout a period during which the rotatable blade member is cutting the web member.
A method for cutting a web member at intervals in a transport direction,
- the web member having a plurality of fibers including tows along the transport direction and being continuous in the transport direction, the method comprising:
- intermittently transporting the web member in the transport direction;
- cutting the web member by moving a disc-like rotatable blade member along an intersecting direction with the rotatable blade member rotating about a rotation shaft during a suspension period of transport of the web member without the rotatable blade member engaging an opposing member,
- the intersecting direction intersecting the transport direction,
- the rotation shaft extending along the transport direction;
- and
- regulating movement of the web member by pressing the web member against the intermittent transport mechanism at a position downstream from a target cut position in the transport direction throughout a period during which the rotatable blade member is cutting the web member.
